01Its name is literal
Blue Tongue earns its name honestly — the sweet, edible berries stain the mouth and tongue a deep blue-purple, a novelty that makes this rainforest-margin native a fun, low-effort planting for warm, humid gardens.
02Planting
Method
Plant from a nursery pot in a part-shaded, sheltered position.
Soil
Humus-rich, moist, well-drained soil; dislikes drying out.
Timing
Plant in the build-up to the wet season, in a warm, frost-free position.
Planting timing varies significantly by Australian climate zone. Set your zone above (or use the Find My Climate Zone tool) for guidance tailored to your own area.
03Growing care
- Keep soil consistently moist — dislikes drying out between waterings.
- Part shade suits it well, especially through the hottest part of the day.
- Mulch well to help retain the moisture this plant needs.
- No frost tolerance — protect or avoid anywhere it gets cold.
04Problems
- Drying out — the most common issue; keep soil consistently moist.
- Cold or frost — limits it to tropical and warm subtropical zones.
- Full sun in hot climates — can scorch leaves; part shade is safer.
- Very few pests — otherwise a trouble-free native.
05Harvest & storage
Signs
Fruit turns dark purple-black and softens, usually through summer and autumn.
Method
Pick by hand once fully soft; expect blue-stained fingers.
Curing
None needed — good eaten fresh, straight off the bush.
Storage
Fridge a day or two; best eaten fresh rather than stored long-term.
Preserving
See Dehydrating (drying for long-term storage) or Freezing Produce (freezing a harvest surplus) for ways to keep a harvest surplus.
